The EVQ6539-V-00A evaluation board is designed to demonstrate the capabilities of the MPQ6539-AEC1, a three-phase, brushless DC (BLDC) motor pre-driver.

The MPQ6539-AEC1 is capable of driving 3 half-bridges consisting of 6 N-channel power MOSFETs up to 80V. The device uses a bootstrap (BST) capacitor (C_BST) to generate a supply voltage for the high-side MOSFET (HS-FET) driver. If the output is held high for an extended period, an internal charge pump maintains the HS-FET.

Internal protections include configurable over-current protection (OCP), adjustable dead-time (DT) control, under-voltage lockout (UVLO), and thermal shutdown.

The driving control signals are generated via an external controller, such as a microcontroller (MCU) or FPGA.

The MPQ6539-AEC1 is available in a QFN-28 (4mmx5mm) package with wettable flanks, and is available in AEC-Q100 Grade 1.
